# Claude Code

> An agentic coding assistant that lives in your terminal — understands your codebase, edits files, runs commands, and manages git workflows through natural language.

Claude Code is Anthropic's official CLI tool that brings the power of Claude directly into your terminal. Tell it what you want to accomplish and it executes the steps: reading your codebase, editing files, running shell commands, creating commits, reviewing PRs, and more — all without leaving your workflow.
